[FMadera]

Libero may only play back row.

Libero must wear a jersey color that clearly contrasts those of his/her teammates.

Libero may serve in only one rotation on the lineup (can be determined when the libero serves, does not have to be listed in advance). (Libero may not serve in USAV.)

Libero must be listed on the lineup.

Libero may not attack a ball if at the moment of contact, the ball is entirely above the net.

Libero may not block or attempt to block.

Libero may bump set from anywhere on the floor. If the libero finger sets the ball from behind the attack line, there are no restrictions on a subsequent attack. If the libero finger sets while in the attack zone, the next contact cannot be an attack contacted from entirely above net height which is then completed. This attack would be illegal.

Whomever the libero replaces (liberos replace, they do not sub, and replacements are not counted toward a team's sub count) MUST replace the libero. It is illegal for another player to replace the libero. The libero may, however, replace any player who is in the back row.

There must be one rally between libero replacements, unless the libero is on the court and will replace into right back in order to legally be the next server.

That's all I can think of off hand...anything anyone else wants to add, or do you have any questions?
